Abstract
A knee joint prosthesis includes a femoral component, a tibial plateau and a tibial bearing member. The design and geometry of the articulation surfaces of the condylar elements of the femoral component and tibial bearing member is such that contact area between the articulation surfaces is maximized both in perfect alignment and in malalignment conditions. Moreover, contact stresses placed upon the articulation surfaces in perfect alignment and in malalignment are reduced. High contact area and low contact stress on the articulation surfaces can be maintained even while matching knee prosthesis components of different sizes.
